Your symptoms could be either hypo or hyper. My bet would be that you're either a little hyper or your levels are just fine but you can't tolerate that does of Synthroid. I need to be on 75mg of synthroid to feel good but it took 5 months to get there. Every little increase gave me hyper symptoms just like yours. Scary as heck and totally interfered with my life. Baby steps finally got me to where I need to be. See what your tests come back as. If they are normal you may just need to lower your synthroid dose and work your way back up.
Thanks for the reply. Did you have a partial thryroidectomy? If so, were you taking meds before surgery?
I had a total thyroidectomy. I had a very large multinodule goiter that decided to act up for about 6 months. Thyroiditis I think my Dr called it. I wasn't on meds before the surgery. No cancer which was good. Anyway, I had to start the synthroid right after surgery. My endo gave me 88mg based on my weight (I was terribly thin at the time). Right away I started to get shaky and lightheaded; had heart palpitations. My levels weren't off but I just couldn't take that much synthroid. Dosed down to 50mg and went hypo; up to 75mg; up to 100mg and it started all over again. Levels were "normal" but I couldn't function. I'm now back on 75mg and everything has evened out. I just couldn't ramp up quickly. Hopefully your blood work will give you some answers.
